Description

Technical Field

[0001] The present invention belongs to the technical field of metal processing equipment, and particularly relates to a surface grinding machine for metal plates. Background Art

[0002] A surface grinding machine for metal plates is a mechanical device used for surface treatment of metal plates, mainly for removing rust, oxide layers, old coatings or burrs on the metal surface, and improving surface finish. Grinding the surface of metal plates usually requires double-sided grinding. However, the traditional grinding machines commonly used for single-sided grinding. After one side of the metal plate is ground, it needs to be manually turned over and then re-entered into the grinding machine for grinding. If a large number of metal plates are ground, such operation will result in low production efficiency. And the double-sided grinding machines on the market usually have high manufacturing costs and high maintenance costs, which increases the production costs of enterprises.

[0003] Impurities such as metal chips generated during the grinding process of traditional grinding machines may adhere to the surface of the metal plate, which greatly affects the effect of coating treatments such as painting after the metal plate is ground and affects the product quality. Therefore, a surface grinding machine for metal plates that can perform double-sided grinding with good cleaning effect is needed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a surface grinding machine for metal plates. The present invention can automatically turn the metal plate during the conveying process of multiple passes of grinding, achieve the effect of double-sided grinding, and can effectively clean the impurities on the surface of the metal plate during multiple passes of grinding. Combined with the comprehensive cleaning of the metal plate during the turning process, it effectively ensures the cleaning effect of the metal plate, prevents the metal plate from adhering to impurities such as metal chips, and affects the final product quality of the metal plate.

[0005] The technical solution adopted to solve the above technical problem is: a surface grinding machine for metal plates, including a fixture mechanism, a limiting shell and a driving mechanism. The fixture mechanism is slidably connected to the driving mechanism. The limiting shell is arranged above the fixture mechanism. The driving mechanism can drive the fixture mechanism to move horizontally. A feeding platform is fixedly arranged at the front end of the limiting shell. A first grinding assembly is fixedly arranged at the front end of the feeding platform. A dust cleaning bin is fixedly arranged at the front end of the first grinding assembly. A second grinding assembly is fixedly arranged at the front end of the dust cleaning bin;

[0006] The feeding platform, the first grinding assembly and the second grinding assembly are all provided with channels allowing the fixture mechanism to pass through;

[0007] The fixture mechanism can clamp the metal plate to be processed, and the fixture mechanism can drive the metal plate to be processed through the first grinding assembly, the dust cleaning bin and the second grinding assembly;

[0008] When the clamping mechanism clamps the metal plate to be processed and passes through the dust cleaning bin, it can drive the metal plate to be processed to flip.

[0009] Through the above technical solution, the metal plate to be processed can be fed from the side of the feeding platform. The driving mechanism drives the clamping mechanism to move forward. After the clamping mechanism clamps the metal plate to be processed, it drives the metal plate to be processed through the first grinding assembly, the dust cleaning bin and the second grinding assembly. When passing through the dust cleaning bin, the clamping mechanism drives the metal plate to be processed to flip, so that the first grinding assembly grinds the front side of the metal plate to be processed, and the second grinding assembly grinds the back side of the metal plate to be processed. And when the metal plate to be processed flips in the dust cleaning bin, the dust cleaning bin can comprehensively clean the metal plate to be processed. Compared with the traditional processing method in which the metal plate is in a horizontal state for cleaning, the cleaning effect is more thorough. After the grinding is completed, the driving mechanism drives the clamping mechanism to return. After the metal plate to be processed falls into the feeding platform, it is then output from the side of the feeding platform, and the grinding process of the metal plate to be processed can be completed.

[0072] During operation, the metal plate 9 to be processed can be fed from the side of the feeding platform 4. The driving mechanism 3 drives the fixture mechanism 1 to move forward. The electric push rod 142 adjusts the distance between the upper clamping plate 15 and the lower clamping plate 16, so that the abrasive papers arranged at the bottom of the upper clamping plate 15 and the top of the lower clamping plate 16 are attached to the metal plate 9 to be processed.

[0073] Raise the lifting baffle 41 to limit the metal plate 9 to be processed. The driving mechanism 3 drives the fixture mechanism 1 to reciprocate horizontally. The abrasive papers arranged at the bottom of the upper clamping plate 15 and the top of the lower clamping plate 16 can polish the front and back sides of the middle part of the metal plate 9 to be processed simultaneously.

[0074] After the front and back sides of the middle part of the metal plate 9 to be processed are polished, lower the lifting baffle 41. The electric push rod 142 adjusts the distance between the upper clamping plate 15 and the lower clamping plate 16 to clamp the metal plate 9 to be processed, and then the driving mechanism 3 drives the fixture mechanism 1 to continue to move forward horizontally.

[0075] The limiting convex rod 13 will sequentially pass through the first straight groove 21, the arc groove 22 and the second straight groove 23. During this process, the limiting convex rod 13 will rotate from one side to the other side, driving the rotating rod 12 to rotate 180 degrees, realizing the flipping of the fixture mechanism 1 clamping the metal plate 9 to be processed, and the flipping process is realized in the dust cleaning bin 7.

[0076] When the fixture mechanism 1 clamps the metal plate 9 to be processed and passes through the first grinding assembly 5, the first roller group 51 supports the metal plate 9 to be processed, and the first grinding belt 52 grinds the upper surface of the metal plate 9 to be processed. When the fixture mechanism 1 clamps the metal plate 9 to be processed and passes through the second grinding assembly 6, the second roller group 61 supports the metal plate 9 to be processed, and the second grinding belt 62 grinds the upper surface of the metal plate 9 to be processed. The metal plate 9 to be processed is flipped before entering the second grinding assembly 6, realizing that the first grinding assembly 5 grinds the front side of the metal plate 9 to be processed, and the second grinding assembly 6 grinds the back side of the metal plate 9 to be processed.

[0077] During the grinding process, the air inlet joint 17 can be connected to an air compressor to let the blowing groove 18 blow out high-pressure air to blow both sides of the metal plate 9 to be processed, effectively blowing out impurities such as metal chips from the metal plate 9 to be processed and preventing the metal plate 9 to be processed from adhering to impurities.

[0078] During the flipping process of the metal plate 9 to be processed in the dust cleaning bin 7, the air blowing joint 82 can be connected to a blower to let the air jet port 71 jet air to clean the metal plate 9 to be processed, so that the air jet port 71 can clean the metal plate 9 to be processed comprehensively. Compared with the air jet cleaning when the metal plate 9 to be processed is horizontal, the cleaning effect is more thorough. Wind shielding curtains can also be hung at the front end and the rear end of the dust cleaning bin 7 to block the air from blowing out of the dust cleaning bin 7, improving the cleaning effect and preventing impurities from splashing.

[0079] After the grinding of the metal plate 9 to be processed is completed, the driving mechanism 3 drives the fixture mechanism 1 to retract horizontally. After the metal plate 9 to be processed enters the feeding platform 4, the electric push rod 142 adjusts the distance between the upper clamping plate 15 and the lower clamping plate 16, and then the metal plate 9 to be processed after grinding can be placed on the feeding platform 4, and then discharged from the side of the feeding platform 4.

[0080] After the front side of the metal plate 9 to be processed is ground by the first grinding assembly 5, it enters the dust cleaning bin 7 for flipping and cleaning. Then, after the reverse side of the metal plate 9 to be processed is ground by the second grinding assembly 6, when the metal plate 9 to be processed returns, it passes through the dust cleaning bin 7 and can be flipped and cleaned again, effectively ensuring the cleaning effect and improving the product quality.

[0081] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
